Description

Adjustable scaffolding work platform

This creation is about a work platform structure, more specifically an adjustable scaffolding work platform.

The traditional eagle frame is basically made of iron pipe and is fixed by a bolt with a round hole. Since the gap between the pin and the hole is large, it is easy to cause a shaking phenomenon, and standing on the platform of the eagle frame is extremely unsafe. Generally, the work of climbing is often set up as a working platform by means of several ladders and pedals, so that workers can stand on high places; but such a conventional work platform takes up a lot of space, and does not have the ability to adjust up and down as needed and to facilitate mobile work. The function of the platform, and even such a conventional work platform, cannot be carried out on the platform safely in a place where the ground level is significantly different. How to solve the above-mentioned shortcomings is the focus of the creative attention and development.

The purpose of this creation is to combine the concept of the scaffolding structure with the height of the working platform and the function of moving on the ground, and the user can work safely at a high place to develop an adjustable scaffolding work. platform.

An inverted L-shaped fixing piece is respectively disposed to overlap the fixing piece 223 protruding from the bottom end of the two right vertical poles 111 (not shown) and the fixing piece 223 protruding from the bottom ends of the two left vertical poles 121. Therefore, the screw is fixed together; therefore, the work platform support portion 2 composed of the two pairs of platform support frames 21, 22 and the two support rails 25 and the work platform 3 fixed on the work platform support portion 2 can be customized according to the needs of the worker. , can slide on the two vertical poles 111, 121 to adjust the height of the working platform 3 As shown by the arrows in FIG. 2; in order to ensure that the working platform 3 after the height adjustment is correctly positioned at the adjusted position, the two ends of the support frame connecting rods 212, 222 located at the lower ends of the two pairs of platform support frames 21, 22 are respectively installed. A fastening device 26 is inserted into the through holes 214, 224 of the lower ends of the platform support frames 21, 22 and the side rails 1111, 1121 between the two vertical bars 111, 112 of the frame portion 1 corresponding to the through holes. The purpose of the work platform 3 after the positioning adjustment is achieved. The step 41 outside the ladder portion 4 resembles the platform support frames 21, 22 of the work platform support portion 2, substantially a pair of each other and having The U-shaped section of the rod is adjacent to the lower end and the adjacent intermediate portion, and is respectively integrated by the two ends of the outer ladder connecting rod 4111 and the upper and outer ladder connecting rods 4112; The two sides of the upright rods 111 and 121 of the segment 42 like the frame portion 1 have two straight rods corresponding to the outer step 41 and have a quadrangular tube section, and two horizontal rods extending at both ends of the plurality of square tube sections. The inner step 42 is slidably sleeved on the outer step 41, and the outer side of the top end of the two sections of the outer step 41 is inclined to fix one end of the first outer step fixing piece 412, and the outer step One end of the outer side of the two-segment of the 41-segment and the upper and outer step connecting rods 4112 are respectively inclined to fix one end of the second outer step fixing piece 413; the other end of the first outer step fixing piece 412 It is fixed to the right platform support frame 21 adjacent to the right platform positioning piece 211, and the other end of the second outer ladder fixing piece 413 is fixed on the outer side of the right platform support frame 21 adjacent to the middle portion thereof, so that the outer step 41 is inclined. Fixed to the right platform support frame 21; therefore, when the work platform support portion 2 moves up and down to adjust the height of the work platform, The segment 41 moves together with the right platform support frame 21, and the inner step 42 can be pulled relative to the outer step 41 to the foot end to contact the ground according to the position where the work platform support portion 2 is moved; It is positioned at the position after the pulling, and is located at the two ends of the outer step connecting rod 4111 under the outer step 41, and a fastening device 44 is respectively inserted into the through hole 414 at the lower end of the outer step 41 and the corresponding through hole. One of the steps is to traverse the rod to achieve the purpose of fastening the inner step 42.

Next, as shown in the third, fourth, and fifth figures, The operation of this creation "Adjustable Scaffolding Work Platform" is explained. Fig. 3 shows the working platform 3 at the lowest height position, at which time the bottom end of the working platform support portion 2 abuts the foot end bottom plates 121, 122 of the frame portion 1. Figure 4 shows that the work platform support 2 and the work platform 3 have been moved up to a height position from the ground. At this time, the outer step 41 is also moved up with the work platform support 2, so that the worker can The work platform 3 is boarded by climbing the inner step 42. Figure 5 shows that when the worker uses the "adjustable scaffolding work platform" on the uneven floor, for example, when working on a high place with a step, in addition to the work platform 3, the height can be adjusted. The two vertical bars 111, 112 of the portion 1 can also be adjusted to move up or down with respect to the work platform support portion 2, and stand at different levels of ground height.

In summary, the creation of the "adjustable scaffolding work platform" has the following advantages:

(1) The combination of the trapezoidal positioning block 31 and the trapezoidal positioning grooves 2111 and 2211, and the bolts 24 with a star-shaped knob are used to lock the two together, so that the creation of the "adjustable scaffolding work platform" is firmly established. On the ground, it is not like the traditional scaffold made of steel pipe. The pin is fixed with the round hole. Because of the large gap between the pin and the hole, it is easy to shake and unstable.

(2) The platform support frames 21 and 22 of the work platform support unit 2 are slidably fitted to the two vertical poles 111 and 112 of the base portion 1, and the platform support frames 21 are inserted by the fastening device 26, 22 through holes 214, 224 The adjusted platform support frames 21 and 22 are affixed to the side rails 1111 and 1121 between the two vertical bars 111 and 112 of the pedestal portion 1 corresponding to the through hole, thereby simplifying the adjustment of the work platform 3 to the required work. Height, no need to rebuild the complex work after the traditional scaffold has to dismantle the steel pipe and work pedal.

(3) The upright rods 111, 112 on both sides of the seat portion 1 can be moved up and down independently of the platform support frames 21, 22, and stand at different levels of ground height, so that the creation of the "adjustable scaffolding work" The platform can be used in the stairwells with different steps to make use of the "adjustable eagle-type work platform" for high-level work to overcome the inconvenience caused by uneven terrain.

(4) The creation of the "Adjustable Scaffolding Work Platform" is made of aluminum material. It is not only lightweight but also strong in structure. It is driven by the caster 123 and has high maneuverability.

Finally, it should be emphasized that the above is a detailed description of the embodiment of the "adjustable eagle-type work platform". Those who are familiar with the technology should understand the structure of the creation, and are not intended to limit the scope of this creation patent. Replacement, change, etc. should still belong to the scope of this creation. The creation of the "adjustable eagle-type work platform" is in accordance with the industrial use, novelty and progress of the patent law. It proposes a new type of patent application according to law, and invites the form to review and grant the patent. Will.
